1972 Chevy 4wd Longhorn Project: Never Ending Changes

[jbclassix]

I've been watching all the guys on here who are shortening beds, studying how they blend in the body curves where they removed the sections... Its gonna be cool to see this bed go the OTHER way! Are you gonna weld the factory longhorn seams?

Looks like some great progress on the Longhorn Ryan. Glad to see your's is coming togther.

I thought about welding it and smoothing it out. But I want it to look some what original. Most people probably wouldn't catch it beeing a Longhorn with out the seem. I like it there too. My luck, I'd weld it and that area would be the only place that body work would crack or I'd get hit there first.

Thanks Mike. It is slow going. How ever, I am working on the engine while I sleep. So maybe by the week's end I'll have it close to beeing ready to drop in.

You're kidding??? Congrats buddy!!

We just passed the big 1st b-day and man was it a blast.

To delete the vacuum pumps can I pull the pumps and pushrods and make cover plates?

Congrats Nate! Izzy's 1st was Jan 21. It was a blast for sure. Little bro's due date is April 14th, but the docs think it will be end of March. Maybe sooner, maybe later. They aren't sure. Imagine that.

On the first gen vacuum pumps, yes you can. I did that on my corvette. I used the vacuum pump to drive the PS pump so I could run hydraboost brakes.

Thanks Ryan,That's what I want to do.If I take them off it will be easy to move the enging back.

You can get the newer style vacuum pump set up and then you won't have to go without a vac pump. 92-98 should be same vac pump. PS pumps, there are 2 different styles. A tear drop shape housing, and a round. Then there is a 1 return and a 2 return for hydra boost set ups.

[mknittle]

Thanks Ryan, that's good to know.i want to use a hydra boost I really like the one I used on my 42 jeep. clears the buick V 6 and has lots of power with a good solid feel.
a vacuum pump may be a good idea for the AC. Its sort of design by the seat of the pants.LOL
Gotta go to a bonsai club meeting Mark

This weekend in between some other projects, I had some help and managed to get some box sides bolted on! Now I'll have to decide if the LH box side is going to be used. I think the one from my original bed is nicer. So we'll see. This metal floor swap isn't going to be as bad as I thought it was going to be!







Sorry about the mess. We've been cleaning up out side since it's been so nice and now it's supposed to rain all week so we had to shuffle stuff around the storage truck.

Here is the new phase of this truck. I don't have a common rail engine any more, and I want to get into tuning on EFI live. My brother happened upon a sweet deal a few weeks ago and now I'm going to build a common rail and put it in the Longhorn. Here are some misc. pics.





The thing in the plastic bags is my block. The turbo is a 76mm HT60 which will be my primary turbo in my compound turbos.

Right now I have most of the big pieces I need for it. Here's what I have for it right now.

05 Block with fresh hone and deck job.
12v crank
181/210 Hamilton cam
06 ECM
05 engine harness
05 CP3
05 injectors
04.5 donor engine for hard ware
12v connecting rods
4 good 05 pistons

What I'm lacking to get it together
Rings, and bearings
Gaskets and seals
2 05 pistons
100hp nozzles
Some misc wiring to get the engine running.

I plan on getting the stuff for it soon so I can try to get it running soon. I was going to buy new pistons for it, but the pistons I wanted were $1000. That's going to have to wait!

I can here the turbos spooling up and see the black smoke already

I'm going to try and keep it smoke free or close too it until the time comes!

Hey ryan nice build Im not much into diesels but what is a common rail?

[ryanroo]

common rail refers to a pressurized fuel rail that is common to all injectors. the injectors are cycled by the computer instead of mechanically via fuel pressure. it has been the dodge system since 03. all current diesels run this type of injection now i believe, in light trucks anyhow.

so, you cutting me a good deal on the 24v with the p-pump swap? haha

ryan

[1985-GMC]

They're trouble that's what they are! lol EFI live should be fun!

Haha no in 03 the common rails came out, they use a CP3 injector pump in which one line fuels a "rail" then the computer controls when the injectors open instead of pressure like on the mechanical systems.

Lookin good ryan! When you cut out a piece of bed floor from a donor are you going to just get the front 15"s or so, so you only have to weld up one seam?

Heavy duty on road diesels are "common rail" that I know of, Detroits might not be but we don't do much with newer ones.

They are the DEBIL!!! But it's a debil we must embrace and test the limits of the dual disc in the truck and see what happens.

[watahyahknow]

havent read a lot about aftermarked ecu's for them other than a re chipping the original computer , it would be nice to see a megasuirt setup working on a diesel

It all depends what you consider a good deal.

You're right on the money except there is no injection pump. Just a lift pump and a high pressure pump.

On the box I have a bed floor patch panel I'm going to use and section it in. I had a hard enough time finding this steel floor so finding a second may take a while.
